摘要：
A linear motor includes a rod-like stator having a field magnet, and a movable piece having an armature coil fitted around the field magnet and arranged inside a cylindrical movable piece yoke. The movable piece is provided at its opposite ends with bearings. The armature coil is arranged between the bearings. The cylindrical movable piece yoke is provided at ends of a lower portion in the gravity direction with projections extending in the movable piece moving direction.
